Phased Application

The EU AI Act was published in the Official Journal of the European Union on 12 July 2024 and entered into force on 1 August 2024. It applies in phases over three years:

Phase 1: February 2025 – Prohibited AI Practices

Status: Already in force since 2 February 2025.

Art. 5 EU AI Act prohibits the following AI practices:

  • Social Scoring by public authorities – evaluating natural persons based on their social behaviour
  • Subliminal Manipulation – AI techniques that unconsciously influence a person's behaviour
  • Exploitation of Vulnerabilities – exploiting age, disability, or social/economic situation
  • Real-time Remote Biometric Identification in publicly accessible spaces (with exceptions for law enforcement)
  • Biometric Categorisation by sensitive attributes (ethnicity, political opinion, religion)
  • Untargeted Scraping of facial images from the internet or CCTV footage
  • Emotion Recognition in the workplace and educational institutions (with exceptions for safety/health)

Penalties: Up to €35 million or 7% of global annual turnover (Art. 99(3)).

Phase 2: August 2025 – GPAI Obligations and Governance

Status: From 2 August 2025

  • GPAI Models (Art. 51–56) – transparency obligations for providers of general-purpose AI models
  • GPAI with Systemic Risk – additional obligations: red teaming, model evaluation, incident reporting
  • AI Literacy (Art. 4) – organisations must ensure that staff involved with AI are adequately trained
  • Governance (Art. 64–68) – establishment of the European AI Office and national competent authorities

Phase 3: August 2026 – High-Risk AI Obligations (Main Deadline)

Status: From 2 August 2026 – approximately 5 months away

This is the most critical deadline for most organisations. From this date, all obligations apply to high-risk AI systems under Annex III:

  • Risk Management System (Art. 9)
  • Data Governance (Art. 10)
  • Technical Documentation (Art. 11 + Annex IV) – Guide
  • Record-Keeping (Art. 12)
  • Transparency for Deployers (Art. 13)

Obligations for AI systems embedded as safety components in already regulated products under Annex I (e.g. medical devices, machinery, toys, lifts, pressure equipment).
